Abstract: 116,448. Goewey, J. M. Oct. 29, 1917. Tyre and like inflating-valves.-Relates to inflating valves and pressure gauges for pneumatic tyres of the kind wherein the gauge itself has an automatic check valve, and consists in the combination with the usual inflating-valve of a dust cap, a gauge member movable in the dust cap, and a graduated piston slidable in the gauge member and capable of being placed under the influence of the pressure in the inflating valve. A hollow graduated piston 14 slides within a tube 4 against the influence of a spring 17. The tube in turn slides within the dust-cap 8 against the influence of a spring 10. It is threaded at 6 to engage a thread 7 on the valve tube, and is provided with a bar 12 for opening the inflating valve. A spring ball valve 21 is arranged at the top of the graduated piston to close normally an inlet hole. Figs. 2 and 3 show the device out of action and in action respectively. The tube 4 is pressed down against its spring and screwed on to the part 7. The bar 12 in this operation engages the valve stem 22 and moves the valve to place the gauge in communication with the tyre. The piston is moved up against its spring and the pressure may be read off. The tyre may be inflated through the ball valve, or the latter may be depressed to deflate the tyre.

Filed: 1937-06-07
Abstract: 493,727. Regulating. AUTO UNION AKT.-GES. June 7, 1937, No. 15771. Convention date, June 6, 1936. [Class 7 (vi)] In two-stroke engines having exhaust ports A and scavenging and charging ports S each controlled by the piston and by additional control members, such as rotary valves 3 and 31 respectively, these control members are regulated so that the ports are opened earlier as the engine speed increases, for example by angular adjustment of the valves. The valves 3, 31 may also be adjusted axially so as to vary the cross-sectional area f of the cylinder ports which is opened by the port in the valves, and of the shaded part f<1> which remains covered by the unported part of the valves. If the valve ports are tapered as shown in Fig. 8, the axial adjustment will effect a variation in both the area and timing.

Title: Method and Apparatus for Producing Nuclear-Fusion Reactions.
IPC: H05H1/03
Filed: 1967-04-06
Abstract: 1,165,550. Nuclear fusion rectors. INTERNATIONAL STANDARD ELECTRIC CORP. 6 April, 1967 [13 May, 1966], No. 15794/67. Heading G6P. In a nuclear fusion device, ion collisons are effected inside a spherical space. A cathode is mounted concentrically within a spherical anode and positively charged ions are caused to oscillate along linear diametral paths through the geometrical centre. The cathode is a metallic open mesh, pervious to the positive particle flow and impervious to electron flow and a virtual anode is formed at the centre, by reason of the space charge distribution. Electrons are also emitted by the cathode due to photo-electric action and add to the energy of the gas through the action of the virtual cathode. Further concentric virtual cathodes and anodes may be formed within the mesh cathode. Fusion occurs by reason of the high particle density at the geometrical centre. In one embodiment, dual concentric cathodes are mounted within a spherical anode maintained at ground potential. Fuel gas ions are injected radially into the central space by guns mounted externally of the anode. The nuclear reactions involved are such as to generate electricity directly at the anode. Alternatively, the device may be used as a heat generator, using a different fuel and reaction. In an alternative construction, a single spherical cathode shell is provided, which has apertures each covered by two meshes. As in the first arrangement, the meshes prevent escape of electrons from the cathode space and inhibit the penetration of the anode positive field into the cathode space, thereby maintaining the spherical field distribution therein. Each ion gun includes a thermionic filament, for generating ionizing electrons, and an anode sleeve with a frusto-conical bore through which the ionized fusion reactive gas stream is directed. In a modification, permanent magnets are mounted outside each gun to cause the electrons to follow larger paths and so increase the probability of gas ionization. The reactions may employ deuterium, tritium or helium.

Abstract: 439,244. Printing-machines. ROWLAND, M. F., 56, Ludgate Hill, London.-(American Bank Note Co. ; 70, Broad Street, Manhattan, New York, U.S.A.) May 28, 1934, No. 15865. [Classes 100 (i) and 100 (ii)] Feeding webs; inking- apparatus.-In a rotary steel-plate printing-machine, a wiping-web is maintained in contact with the plate cylinder over a limited area by one or more platen rollers continuously rotated in the same direction as, but at a lower speed than, the plate cylinder, whereby also the web is fed forward, rewind mechanism being utilized solely to take up the slack ; feedrollers advance the web from the supply roller to the platen rollers. The wiping-web 16 passes from the supply roll 14 between feed-rollers 24, 25, round two platen rollers 26, 27 and a floating roller 34, and thence to the rewind roll 18. The rollers 24, 26, 27 and the roll 18 are shown as driven from friction discs 45 mounted adjacent the end of the plate cylinder 10 and driven therefrom through gears 48, 47. Springs 51 press the discs outward from plates 49 on the shafts of the gears 47, and the plates 49 and discs 45 are coupled together by pins and provided with studs to prevent excessive compression of the springs 51. Engaging the discs 45 are friction wheels 42, fast to worm-shafts 40, 41 slidably and rotatably mounted in the frame of the machine and engaging worm-wheels 36, 37 on the shafts of the platen rollers 26, 27. The worm-shaft 40 for the first platen roller 26 also engages a worm-wheel 54 on the shaft of the feed-roller 24, and also drives, through sprocket-gear, the rewind roll 18. The platen rollers 26, 27 are mounted in radially slidable bearings which are adjustably spring-pressed towards the plate cylinder. The pressures of the two platen rollers 26, 27 may be varied to share the wiping effect between them in different proportions. A polishing-web 84, which may be of dampened muslin, passes over a similarly mounted platen roller 66 in a direction opposite to that of the movement of the plates on the plate cylinder, to feedrollers 64, 65 and a rewind roll 58.
